Air handling unit cleaning in Wellow, Isle of Wight
AHU cleaning across Wellow and nearby, booked around your opening hours and finished with a written report and photos.
- Air handling units due a clean after building work
- Dust-coated heating and cooling coils
- Units that have only ever had filter changes
Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Make sure the unit’s access doors open easily
- Don’t ignore odours coming through the grilles
- Do not store bins or materials near the intake
- File each AHU report in the maintenance log
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
AHU cleaning in Wellow
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and give you a fixed quote, so you know where you stand. If you have leaves and litter drawn into the unit and dirty fans and fan housings, we can put it right.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
The report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

How it works
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Visits to a village like Wellow are booked in advance, at a time that suits whoever runs the site.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Have your last certificate or report to hand
- Arrange a key holder or contact on site
Getting a quote
We do not publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To get going, ring 0345 646 2711 or drop us a line.

When something else is needed
A few issues sit outside what this work can do:

- Dirty ducts beyond the unit itself
- Mechanical faults with motors, belts or bearings
If in doubt, call 0345 646 2711, or send details by email and we’ll say what we think.

When to call us in Wellow
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
If you notice any of these, it’s worth a diagnosis:
- Dirty fans and fan housings
- Air handling units with blocked filters
- Rooms that smell stuffy when the system runs
- Plant that needs cleaning after a refit
If you manage a school such as Shalfleet Church of England Primary School, ventilation cleaning is best booked for the holidays.
What your quote should include
- Whether the work can be done while the site is closed
- If they look at the system before pricing
- When the next visit should be, and why
- What paperwork you get at the end
FAQs for Wellow
Do you work at weekends in Wellow?
Yes, nights and weekends are routine for us. The work in Wellow can fit around your hours. Let us know the hours you’re closed and we will book within them.
Do you cover smaller places like Wellow?
Yes. Villages and rural sites across the South East are part of our work, Wellow included. Photos of the system and directions to the site help us plan the visit.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Can you quote from pictures?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
What’s TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
What should I send you?
Some photos and a quick description of the system, with the address and opening hours. If we need more, we’ll ask.

Our area takes in London and the South East, Wellow included. Visits are booked around your hours, evenings and weekends included.
In Wellow, we look inside the system before deciding what needs cleaning.

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
What affects the cost of AHU cleaning
Sites vary more than people expect. What affects the quote:
- A single visit or a regular plan
- Whether we need access equipment or extra panels
- The condition of the system
- The times the site is available
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
What to send for a quote
When you contact us, it’s useful to have:
- The times we could work without disrupting the site
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
- Photos showing the whole system and its surroundings
To get a fixed quote, call us on 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll typically have a quote within one working day.
What else we do in Wellow
How the job changes from site to site
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
